CHARLES F. HIPPARD, OF MINONK, ILLINOIS.

VINE AND WEED CUTTER.

Specification of Letters Patent.

Patented March 26, 1907.

Application filed. August 10, 1906. Serial No. 330.015.

To all whom it may concern:

Be it known that I, CHARLES F. HIPPARD, a citizen of the United States,and a resident of Minonk, in the county of l/Voodford and State ofIllinois, have invented a new and Improved Vine and l/Veed Cutter, ofwhich the following is a full, clear, and exact description.

The purpose of the invention is to provide a vine and weed cuttingattachment adapted for ready application to any type or size ofcultivator and which will accomplish most effective work in killing anykind of weeds or vines that may be outside a row of corn, for example.It not only cuts and entirely eradicates the weeds or vines, but itpushes them midway between the rows.

Another purpose of the invention is to so construct the knives and theattaching mediums therefor that the knives will be in front of thecultivator-blades practically parallel with their alinement, yetsufliciently far removed from said cultivator-blades as not to interferewith the functions of the latter.

It is also a purpose of the invention to so construct the attachmentthat the knives thereof can be set to run deep or run shallow, as theconditions of the ground may require. Should the ground be loose, itwould be necessary to set the knives deep enough to catch the vines insolid ground to insure their complete extermination; but should theground be hard and packed the blades may be set just so that they willdo the work, and in either event there is but slight difference in thedraft of the plow.

Another purpose of the invention is to construct a vine or weed cutterthat will work through trash and not become clogged and which willprevent the vines or weeds from getting on or clinging to the beams ofthe cultivator, and wherein the cultivator will have a good clean groundto work over, thus rendering the cultivation of a field more perfectthan it is possible to effect without the cutting attachment.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of a cultivator and applied cuttingattachment. Fig. 2 is a plan'view of the cultivator and attachment. Fig.3 is an enlarged detail plan view of the right-hand cutter and the firstcultivatorbeam. Fig. 4 is an inner face of the parts shown in Fig. 3.Fig. 5 is a vertical section taken practically on the line 5 5 of Fig.3, and Fig. 6 is a detail view of a bolt used for adjustably attaching asupporting-standard to the knife.

The cultivator herein shown is provided with six shares or shovelslocated in a gang of three at each side of the draft-beam B. Theseshovels or shares are designated, respectively, as A, A, and A and theirbeams are designated, respectively, as a, a and 0, The rear beams a areconnected with the draft-beam B by a cross-bar 10, and handles 11 aresecured in the customary way upon the said draft-beam B, whichterminates at its forward end in a suitable clevis 12. All of thecultivator-beams a, a, and a are connected to the forward portion of thedraftbeam B by a single bolt 13.

In connection with each gang of cultivator shares or shovels a knife Cis employed. Said knives are located outside of said gangs of shovels,as best shown in Fig. 2, being separated from their outer edges by aboutfive or six inches, so that the knives will not interfere with thefunctions of said shovels, and the knives are supported from the frontand the rear cultivator-beams a and a in such manner that the knives Care practically parallel with the gangs of shovels.

The knives O extend beyond the forward shovels and likewise beyond therear shovels, as is shown in Fig. 1. Each knife is provided with alongitudinal keeper 14.- upon its rear face, a keeper being located neareach end, and each keeper is provided with flanges 15 at its ends,apertured to receive bolts or rivets 16, whereby to secure the keepersto the knives. Each keeper is provided also with a longitudinal chamber17 open at the back, and with a longitudinal slot 18 in its inner faceconnecting with the aforesaid chamber 17, as is best shown in Fig. 5.

The chamber 17 of each keeper 14 is rectangular in crosssection andreceives a correspondingly-formed head of a bolt 19,whose threaded endextends out through the slot 18 in the keeper, and the outer end of thebolt 19 is provided with a nut 20. A standard 21, solid or tubular, isprovided with each keeper 14, and the lower ends of said standards 21roo are flat and are given a slight downward and outward inclination, sothat when the flattened portions of the standards are secured to theknives through the medium of the aforesaid keepers and bolts the knivesare given an outward and downward inclination, which tends to throw offthe material cut from the ground and likewise renders the cutting edgeof the knives more effective, the said cutting edges 23 of the knivesbeing beveled upon their inner faces, as is shown in Fig. 5.

The standards are attached to the knives by passing the bolts 19 throughapertures in the flattened portions of the standards and then screwingthe nuts 20 to place. It will be observed that the bolts 19 areadjustable longitudinally in the keepers 14, thus rendering it possibleto adjust the knives to different types and sizes of cultivators, andthat the bolts are held from turning in the keepers by reason of thepolygonal formation of their heads and corresponding cross-sectionalformation of the chambers in which said heads are entered.

A bearing D is employed in connection with each standard 21 toadjustably connect the upper ends of the standards with thecultivator-beams to which they are to be attached. Each bearing Dconsists of a body portion having its inner face flattened to engagewith the outer side face of a cultivatorbeamthe beam a, for example-asshown in Fig. 5, and the said body of the bearing is provided with anupper horizontal flange 24 and a lower horizontal flange 25, adapted toengage, respectively, with the upper and the lower edges of thecultivator-beam, as is also shown in Fig. 5.

At the central portion of the outer face of each bearing D a verticalsegmental groove 26 is produced, extending from top to bottom of thebearing, in which groove the upper portion of a standard 21 is received.A projecting eye 27 is produced upon the upper edge of each bearing D,while a similar eye 28 is formed at the lower edge of the bearing, thetwo eyes being diametrically opposite. The threaded ends of a U-shapedclip 29 is passed through these eyes 27 and 28, and consequently passesat the top and bottom of the cultivator-beam, as shown in Fig. 4, andthe body portion of said clip has firm bearing against the outer face ofthe standard 21 in engagement with the bearing to which the clip isapplied. A backing-plate 29 is apertured to receive the end portions ofthe said clip 29, and the said backing-plate has bearing against theinner side face of the cultivator-beam diagonally thereof, as also shownin Fig. 4, and said. clip is held locked to the beam by suitable nuts28", secured to the ends of the said clip. Thus it will be observed thatthe knives may be adjusted up or down, as may be occasioned by thecharacter of the ground, to cause the knives to cut more or less deeply.

A guard E is located above the upper edge ward inclination, as is shownin Fig. 5, so as to facilitate the shedding off of the turned-up and cutvines and weeds.

Preferably the guards are wider at their forward ends than at any otherportions in their length, as shown in Figs. 1 and 4, since at suchpoints they have the most duty to perform, and each guard E is providedwith a downwardly-extending member 30 at its forward end. This member issecured to the inner face of a knife C as close as possible to itsforward edge, the attachment being made through the medium of suitablebolts and nuts 31 or their equivalents.

If in practice it is found desirable, the guards E may be adjustablysecured to the knives, in which event it is simply necessary toduplicate the holes in the knives through which the bolts attaching theguards to said knives pass.

Having thus described my invention, I claim as new and desire to secureby Letters Pattent 1. The combination with a cultivator, of knivessupported parallel with the shovels on the cultivator, and a guardlocated at the upper edge of each knife and spaced from said ed e.

In a cultivator, knives adapted for en.-
